It's type can include slope data, such as 45 degree slopes, or convex slopes. * Understand that for any type including a slope (types 2 to 29) the Tile must be SQUARE, i.e. have an equal width and height. * Also note that as Tiles are primarily used for levels they have gravity disabled and world bounds collision disabled by default. * * Note: This class could be massively optimised and reduced in size.
